Automated Nucleic Acid Purification Systems

Ask whether the pipetting head passes a volume accuracy check and whether the magnet and heater modules still hold specification. Request the run count and confirm the deck sensors and gripper move without fault. A seller able to run a short verification protocol gives you real evidence rather than a paper claim.

Match the deck capacity to your busiest day rather than your average, since batching is where automation pays off. Compact units handle a strip or part plate, while plate based instruments clear a full 96 well block unattended. If your volume swings widely, a mid capacity platform often gives the best balance.

Check that the tips, plates and any sealed cartridges the instrument uses remain in production before you commit. Discontinued consumables can strand an otherwise sound platform. The seller can usually confirm current supply and any generic alternatives that fit.

Many are designed to sit in line between extraction and library prep, but the plate formats and transfer method need to line up. Confirm the output plate matches what your next instrument expects. Where a handoff is manual, that is usually a minor workflow note rather than a blocker.

Each listing carries a direct line to the seller, so you raise questions about run history and options straight away. There is no intermediary passing messages back and forth. That direct contact means you get technical detail from the person who actually owns the instrument.
